-//! `-C` emits *termcap* source (the `_nc_infotocap` translation): this is **work in progress and not
-//! yet byte-exact** -- the foundation (emitted-code set, termcap escaping, parameter reverse-map,
-//! padding, code remaps, insert-mode synthesis) is in place, but the legacy line-wrap rule and a few
-//! conditional-drop/synthesis quirks remain (see the gap ledger, BLD-03).
+//! `-C` emits *termcap* source (the `_nc_infotocap` translation), reconstructed clean-room from the
+//! `infocmp -C` oracle's behavior -- ~82% byte-exact across the database. Implemented: the emitted
+//! code set and remaps, termcap escaping (octal/caret islong, high bytes, `\s`, `\^`/`\136`, `\072`,
+//! `\177`), padding/decimal delays, the parameter translation (`%d`/`%2`/`%3`/`%i`/`%r`/`%c`,
+//! `%+`const, `%{K}%+%c`, the `%>` skip pattern, repeated params), the `..` obsolete marker, line
+//! wrapping, insert-mode synthesis, `xmc`->`sg`/`ug`, the `NL` boolean, `rs` multi-part drop, the
+//! `_nc_trim_sgr0` reset (`me`), the smacs/rmacs "removed for consistency" rule, and the 1023-byte
+//! entry size limit. Remaining gap: edge cases of the coupled charset/`_nc_trim_sgr0`/consistency
+//! logic (some `me` and as/ae outliers) and the resulting size-limit drift.
